RE: 120sp surging
so what is this carb problem, if it reaches full throttle before its all the way open, do i set it up to not open all the way, it ran perfect on the stand, will the tetra tank keep it from foaming?? also i mean the exhaust is so hot that i almost caught wood on fire on the test stand, that is a bit hotter than my ys i think, but i think i have that issue fixed, i mainly need to fix the surging. I think the foaming fuel is the problem, it idles great. i will run it with the cowl off next to see if bubbles are entering the tank.
